Paterson Graduate .

A measuring graduate for mixing and measuring darkroom chemistry.

Calibrated in metric, Imperial, and US scales so you can work from any set of chemistry instructions without converting. The transparent polystyrene is easy to read and resistant to most photographic chemicals.

The 300ml size handles single-reel developer quantities. The 1200ml has a tip-free base and dripless spout for mixing stock solutions. The two together cover the whole process.
